    CAMBIO CLIMATICO: EFECTO SOBRE LA REEMERGENCIA DE ENFERMEDADES INFECCIOSAS Y PARASITARIAS

    Abstract

    EI climate change is a recognized threat whose impacts are occurring at multiple levels and has resulted in the establishment of conducive to the emergence and reemergence of infectious diseases epidemiological scenarios. In order to evaluate the influence of climate change on the presentation of infectious diseases in EI climate change is a recognized global threat, whose impacts are occurring at multiple levels, resulting a new and proper scenario to the establishment the emergence and reemergence infectious diseases. In order to evaluate the influence of climate change on the presentation of infectious diseases in domestic animals, a descriptive statistical analysis was performed by comparing the epidemiological situation in the Sancti Spíritus province at the end of 2008 - begining of 2009, and the end of 2013.The evolution of average annual temperature and rainfall from registers from four weather stations in the region in the period were evaluated and related with epidemiological situation previously described. Research was divided into two directions: i) the collection of epidemiological data (focal and mortality) and ii) the propensity of the physical environment (temperature, rainfall, relative humidity and infestation by rodents). The results show significant increases values of the annual average temperature between 2013 and the rest of the years under study. Relative humidity and rainfall in the period, mainly in 2012 were also increased significativily. During the period new diseases, besides those already reported, they do not appear, but there is an increased number of outbreaks and mortality from disease such as, Pasteurellosis, Anaplasmosis, and Fasciolosis in cattle, equine Lymphadenitis, Coccidiosis in rabbits, were observed. Migration to human ecosystems by rodents were evidenced by increasing percentage of annual averages of infected human ecosystems. It was concluded, that for 5 years ecosystems evolved as a result of climate change, rising temperatures, rains and flooding, spreading of disease and aggressive properties of etiologic agent, were increased, so a detailed study of these diseases patterns is recommended using predictive modeling approaches, because preparation for climate change and its consequences is vital; to assume with responsibly. Domestic animals a comparative analysis of the epidemiological situation in the province of Sancti Spiritus at the end of 2009 and 2013 is performed comparatively. The results show increases in the values of the average annual temperature, relative humidity and rainfall in the period, new diseases do not appear in addition to those already reported but an increase of the focal of pasteurellosis, anaplasmosis is manifested, and Fasciolosis in cattle, Equine Infectious anemia, Coccidiosis in rabbits and classical swine fever in pigs, following the occurrence of weather events.

    Resumen

    Con el objetivo de evaluar la influencia del cambio climático sobre la presentación de enfermedades infecciosas en los animales domésticos se realiza un análisis estadístico descriptivo comparando la situación epizootiológica de la provincia de Sancti Spíritus al cierre de los años 2009 y 2013 y la evolución de las medias anuales de temperaturas y precipitaciones de cuatro estaciones meteorológicas de la provincia. Los resultados muestran aumentos significativos de los valores de la media anual de temperatura entre el año 2013 y el resto de los años en estudio, humedad relativa y precipitaciones en el periodo, fundamentalmente en el año 2012 previo a la aparición de nuevos focos. En el período no aparecen nuevas enfermedades además de las ya reportadas, pero se observa un aumento del número de focos y de la mortalidad a causa de enfermedades: Pasterelosis, Anaplasmosis, y Fasciolosis en bovinos, Linfoadenitis equina, Coccidiosis en conejos y Ectima contagioso en ovinos. La migración al ecosistema humano por roedores quedó evidenciada por el aumento del porcentaje de las medias anuales de locales infectados. Se concluye que durante 5 años los ecosistemas evolucionaron a consecuencia del cambio climático, al aumento de las temperaturas y posterior a la ocurrencia de eventos meteorológicos de gran magnitud como lluvias e inundaciones, favoreciendo la difusión de enfermedades y la agresividad del agente etiológico.
